Calcite is a versatile and beautiful calcium carbonate mineral found in sedimentary and metamorphic rocks worldwide. It occurs in a wide range of colours, from clear and milky white to soft pinks, yellows, and greens, often forming stunning rhombohedral crystals or layered formations. Historically, calcite was associated with cleansing and protection, believed to enhance clarity of thought. Metaphysically, it is valued for amplifying energy, balancing emotions, and supporting spiritual growth, making it a popular choice for collectors, healers, and those seeking harmonious, uplifting energy.
